【摘要】 基于应变模态法结构损伤识别技术作为动态识别方法的一种,其理论依据为利用模态应变能分部来确定结构的损伤位置,本文以此为出发点,通过建立简单多跨简支桥梁模型验证性的分析研究,为该法的进一步应用于工程提供参考。更多还原

【Abstract】 The technology of structural damage identification based on the strain modal method is a kind of dynamic recognition method,and its theoretical basis is to determine the damage location by using the distribution of mode strain energy.Through the analytical study of the modal method of multi-span simply supported sridge,this paper provides the reference for the further application in engineering.更多还原
